This class, CNewMenu, implements owner drawn menus derived from the CMenu class. The goal of this class is to have menus with the same look as the new menu from Microsoft products with Icons and Title support. I was inspired from the great class BCMenu from Brent Corkum. I took some ideas and almost every function but reimplemented almost all of the code and expanded it with some other nice functions. It was a hard work to change the look of the whole menu that belongs to an application - changing the border and adding shading. Furthermore, it was tricky changing all menus under windows 2000 or system menu under Windows XP when you are using themes. Over all, I hope it's now easy enough for you to use this class in new applications.
This new menu works under Windows 95/98/Me and Windows NT4.0/2000/XP. When you would like to use Chinese or some other special characters, you can compile your project with Unicode support. But keep in mind you must have installed the Unicode libraries with Visual Studio, otherwise you get a linking error.
Additionally, when you want your program to work on all platforms, you have to compile it with Visual Studio 6.0. I did not find out why the drawing didn't work correctly when it was compiled with Visual Studio 7.0 under Windows NT 4.0. Furthermore, when you do not like the flat border you can use the STYLE_XXX_NOBORDER and then menus will have the standard menu border like the system.
CNewMenu works also on those systems, but you don not have all features. So the new menu style office 2003 has only the standard menubarcolor, because changing of menubar- or menubackground is not supported on those systems. When you use the new Visual Studio 7.0 / 7.1 you must #define WINVER 0x0400 and then you won't get a runtime error.

It's also possible to add a title to a menu. You can add a title on the top or on the left side of a menu. You can have a gradient or a solid color as a background. With the function SetMenuTitle you can add or remove a title from a menu. The gradient drawing also works on Windows 95.
// Set a title to the system menu
m_SystemNewMenu.SetMenuTitle(_T("New Menu Sample"),
MFT_GRADIENT|MFT_LINE|MFT_CENTER);

Under menu style |
CDialog, CFrameWnd, CMDIFrameWnd, CMDIChildWnd, CMiniFrameWnd and CMultiDocTemplate with the new classes CNewDialog, CNewFrameWnd, CNewMDIFrameWnd, CNewMDIChildWnd, CNewMiniFrameWnd and CNewMultiDocTemplate in your project.
CWinApp's implementation, set the menustyle just before you create the frame or a dialog window in the function InitInstance. // Set drawing style of all menus to XP-Mode or STYLE_ORIGINAL
CNewMenu::SetMenuDrawMode(CNewMenu::STYLE_XP);
CNewMultiDocTemplate* pDocTemplate;
pDocTemplate = new CNewMultiDocTemplate(IDR_MDINEWTYPE,
RUNTIME_CLASS(CMDINewMenuDoc),
// custom MDI child frame
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMDINewMenuView));
AddDocTemplate(pDocTemplate);
// Loading toolbar icons into the menu
pDocTemplate->m_NewMenuShared.LoadToolBar(IDR_DRAWBAR);
m_DefaultNewMenu.LoadToolBar(IDR_MAINFRAME);
InitInstance. // Set drawing style of all menus to XP-Mode
CNewMenu::SetMenuDrawMode(CNewMenu::STYLE_XP);
CDialog to CNewDialog in your Project.
OnInitDialog function after calling the base class function. // CDialogDlg could be your Dialog.
BOOL CDialogDlg::OnInitDialog()
{
// Call the baseclass
CNewDialog::OnInitDialog();
// Load icons to the menu
m_DefaultNewMenu.LoadToolBar(IDR_MAINFRAME);
}
OnUpdate-handler like in a frame window for updating menuitems. When you want to have the standard handling of menu in your dialog you should overwirte OnInitMenuPopup likecall of the update handler change in your // For disable automatically
void CDialogDlg::OnInitMenuPopup(CMenu* pMenu, UINT nIndex,
BOOL bSysMenu)
{
CNewFrame<CDialog>::OnInitMenuPopup(pMenu,nIndex,bSysMenu);
}measureitem, menuchar and initmenupopup. For this purpose I use the CNewFrame template class. So you can replace CYourSpecialBase with CNewFrame<CYourSpecialBase> in your project.
IMPLEMENT_DYNAMIC, IMPLEMENT_SERIAL or IMPLEMENT_DYNACREATE to sub-class the new one. IMPLEMENT_DYNAMIC(CYourNewSpecialFrame, CYourSpecialBase)
BEGIN_MESSAGE_MAP. BEGIN_MESSAGE_MAP(CYourNewSpecialFrame, CNewFrame<CYourSpecialBase>)
//{{AFX_MSG_MAP(CYourNewSpecialFrame)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
OnCreate function.
BOOL InitInstance() function from CMultiDocTemplate to CNewMultiDocTemplate: CNewMultiDocTemplate* pDocTemplate; pDocTemplate = new CNewMultiDocTemplate(IDR_MDINEWTYPE, RUNTIME_CLASS(CMDINewMenuDoc), // custom MDI child frame RUNTIME_CLASS(CChildFrame), RUNTIME_CLASS(CMDINewMenuView)); AddDocTemplate(pDocTemplate);
// Loading toolbar icons into the menu pDocTemplate->m_NewMenuShared.LoadToolBar(IDR_DRAWBAR); // Set drawing style of all menus to XP-Mode CNewMenu::SetMenuDrawMode(CNewMenu::STYLE_XP);
CMainFrame) from CMDIFrameWnd to CNewMDIFrame in the definition and implementation file. // Change the base class in the following makro IMPLEMENT_DYNAMIC(CMainFrame, CNewMDIFrameWnd)
// don't forget to change here the baseclass BEGIN_MESSAGE_MAP(CMainFrame, CNewMDIFrameWnd) //{{AFX_MSG_MAP(CMainFrame) // NOTE - the ClassWizard will add and remove mapping macros here. // DO NOT EDIT what you see in these blocks of generated code ! ON_WM_CREATE() //}}AFX_MSG_MAP END_MESSAGE_MAP()
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) for loading bitmap in the default menu: m_DefaultNewMenu.LoadToolBar(IDR_MAINFRAME);
CMDIChildWnd to CNewMDIChildWnd. Do the same for all derived classes.
InitInstance. // Set drawing style of all menus to XP-Mode CNewMenu::SetMenuDrawMode(CNewMenu::STYLE_XP);
CDialog to CNewDialog in your Project.
CMainFrame) from CFrameWnd to CNewFrameWnd in definition and implementation file.
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) for loading bitmap in the default menu: m_DefaultNewMenu.LoadToolBar(IDR_MAINFRAME);
Sometimes it would be nice to change the menu in a message box or in a CFileDialog Unfortunately, a MessageBox has no base class for overriding. Another problem is the file dialog. There are at least two dialogs and the CFileDialog only sub-classes the child dialog of the FileDialog displayed. For those and other dialogs, I added a special sub-classing mechanism.
// Subclass dialog with system menu
CNewMenuHelper myHelper(NEW_MENU_DIALOG_SUBCLASS|NEW_MENU_DIALOG_SYSTEM_MENU);
AfxMessageBox(_T("You must restart the application"), MB_OK);
What can one do when he or she deso not want to have a menu border replacing in the next dialog displayed? It is very simple! Just place the CNewMenuHelper before your call like in the following sample.
// Subclass dialog with normal border painting
CNewMenuHelper myHelper(NEW_MENU_DEFAULT_BORDER);
AfxMessageBox(_T("You must restart the application"), MB_OK);
The MFC library replaces some colors depending on the chosen system colors. When you use a black line in the bitmap, the color black will be replaced with the system color of COLOR_BTNTEXT. Following the color mapping map. By the way, it is the same color mapping of the toolbars.
The color RGB(0x00,0x00,0x00) will be changed to COLOR_BTNTEXT (black)
The color RGB(0x80,0x80,0x80) will be changed to COLOR_BTNSHADOW (dark gray)
The color RGB(0xC0,0xC0,0xC0) will be changed to COLOR_BTNFACE (bright gray)
The color RGB(0xFF,0xFF,0xFF) will be changed to COLOR_BTNHIGHLIGHT (white)
There are several possibilities for adding icons to a menu. An easy way is with a toolbar resource. But developer studio only supports 16 colors for toolbar-bitmaps. What you can do is: first define your toolbar then replace the saved toolbar-bitmap with a hicolor bitmap by hand. Additionally, you can define every icon in a different bitmap and assign it to a menu item. My way was to define a bitmap like in an image list, make a helper table with the resource id of the bitmap and the size of an icon followed by the ids of the icons. The end of the table must be marked with the id number NULL.
// Define the table
static WORD ToolId[] =
{ IDR_NEWMENU256, // Resource id of the bitmap-icons
16, 15, // Dimension of each icon
ID_FILE_NEW, // First icon's ID
ID_FILE_OPEN, // Second icon's ID
ID_FILE_SAVE, // and so on...
NULL}; // Marker for end of table
//Load the definition into menu with transparent color
m_DefaultNewMenu.LoadToolBar(ToolId,RGB(192,192,192));
It is very simple to add or change the title of a submenu entry when you know the menu text. The helper function ModifyODMenu can be used.
// set the icon IDB_MORE_C to the submenu "More A" m_NewMenuShared.ModifyODMenu(0,_T("More A"),IDB_MORE_C);
It was strange to find that under Windows 2000 you have a window menu with handle 0x10012 which is shared by all applications. (I think under Windows 98 the menu is 0x0090). I don't know why but this is also a reason of the specialty for some effects belonging to the sub-classed menu. First, when you have disabled menu effects, the menu windows are alternating created or shown. That means the first shown menu is mostly the special menu - never created nor destroyed - only shown and disabled, and the second is created normally and destroyed after closing. The third time, sometimes, the special window is shown again and then the next menu is created normally. For this reason, when you sub-class the special menu, you are responsible for restoring all values before unsub-classing it. Be careful when you change some flags or styles, because the other applications like having the standard menu. You can also receive bluescreens when you forget to unsub-class or when changing painting areas belonging to that menu. This is really ugly! Second, when you enable menu effects every displayed menu is created from scratch. For this reason it doesn't matter if you don't restore all flags or styles!
Let me explain how I got the goal to sub-class all menus. First, you can't sub-class the system menu class #32768 of an application; I was also looking for other possibilities. I decided to create a windows hook for all windows messages and catch all messages for creating a window. After checking for the window class, when I found the menu class, I subclassed it. But how I can sub-class the special menu, which is never created? I found that one of the first messages which were being sent to that menu, was 0x01E2 and one of the latest WM_SHOWWINDOW. So I caught these messages for sub- and unsub-classing the special menu. Only between those two messages do you have access to the special window! I don't know why, so be careful.
After I sub-class the menu window I can draw the border by by processing WM_NCPAINT message. But how is the shading effect created? Just before the menu is shown on the screen I save the menu region in a bitmap. This is the reason why it does not work when the background has been changed. Then I combined it with a shadow drawing. Another way would be using layered windows, but this will not work on all systems like windows 95/98.
Since Windows 98 or Windows 2000 it's possible to set a brush for menu and submenus. So it's easy to change the color. But how can we have a gradient in the bar? Well you define a bitmap-brush with the width of the screen and set it to the menu of the frame menu. Are there any clues more? Oh yes, on non NT system like Windows98/Me you have to set the brush origin for not to have an offset with the bitmap when you repaint a part of the menu bar item.
I thought owner drawing a menu is easy all the time, but on Windows XP, with themes enabled, it is a problematic thing - especially the main frame when the system menus were displayed. Instead of owner drawing, the menu items were drawn by the frame. The frame had painted the windows button of the width of the menu at the place of the menu item instead of drawing it, so I found a work-around. I increased the menu item's identifier before showing the menu and restored it after closing it. So it works under Windows 2000 and XP.
You should never stop debugging when you are in middle of painting the menus because the special menu wouldn't be restored or unsub-classed. Furthermore, there were a lot of strange effects. It is not forbidden but be careful and have a lot time for rebooting the system when it doesn't work correctly after stopping the debugger.
CNewToolBar can only be used with CNewMenu. In your project you need to replace CToolBar with CNewToolBar. Additionally when you like to have the dokingbar in the same color as the menu bar you must define USE_NEW_DOCK_BAR before you include newmenu.h.
